CAR-DOOR ltECI-IANSM.

l Application filed April 7,

To all fio/rom `it may concern:

lle it known that l, Brin-:s W. Kennt.,

a. citizen of the United States, residing ati Baltimore, in the county oit Baltimore and Stateof Maryland, have invented certain new and useful Improvements in Car-Door Mechanisms; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains tomake and use the same.

.il'iorm of door arm adapted :tor engagement with a suitable supporting member attached to the car body. A still vfurther object is to provide a door support-hookspecially adapted for use with a door-prying lever.

`With such objects and others in view the invention consists of the construction, combination and arrangement ot parts as will. beherein described and particularly claimed.

'In `the accompanying drawings, which show aprcterred form ot the'invention, Figure 1 is a ifragmentary'side elevational view ot the hopper portion of an ordinary twin hopper car, the saine being equipped with a door mechanisnrconstructed in accordance withthe principles olf the present invention. ln this ligure the door is .shown `as locked in completely closed`1msil1ion.

. llliguri-i. 9. is a similar` view showing the door held in a preliminary position oit `partial closure. lin this view the outer pivot plate is removed and a portion of the door arm is shown in section for a more clear disclosure of certain tea-tures of the inven-` tion. .Figure 3 is an end elevational view of a `corneroi a door, this view being seen in the `direction ot arrow A of Figure 1." Figurel l is a transverse sectional view through a corner of the hopper and a portion of the door, this view being taken on thev line le-4 ot Figure 1. Figure 5 is a fragmentary sectional view taken through a portion of the hopper and hook mechanism, the view being substantially on the line 5 5 olf Figure 1. i

Referring now to these drawings the car,

1923. Serial No. 630,483.

which is ot the twin hopper type, is constructed with an end hopper sheet 1 and a sloping floor sheet 2, the floor sheetbeing flanged up along its side edge and at# tached to the end sheet 1 'by means of rivets such as 3. The' lowermost edge e of. the sheet 2, together with the side edges of the end sheets 1, deiine a hopper discharge opening such as is well known n the art. This opening is normally closed by means ot a door 5 which is provided with outstanding iianges along certain edges, such lor example as is shown for the side edge ot the door at 6. isriveted to the inner tace ot' the sheet 1 by means ot rivets 8 and serves also as a seat i'ior the door 5. This member is prel`1 erably olf tapered cross section so as to deflect the material from the car and prevent it iti-om hanging up when the loadis dumped. The door 5 is hinged to the car at apoint some-what above the ail. 'lhe hinge pintles which extend transversely ot the car in the usual manner are not shown in the drawings as this construction is well known in the art.

The door 5 is supplied on its outer tace and near the lower edge thereof with a transverselyextending stiffening member 9 which ordinarily constitutes a door spreader tor uniting two aligned doorsot a pair. This arm is, in the present embodiment, formed of a sliecial channel made up by Hanging a steel plate. One I'lange l() ot the cluumel lies against the outer face of the door plate and is secured thereto by means olf rivets 1l. 'lhe other flange 17 extends substantially parallel` with the door plate and somewhat removed therefrom. The end oit the channel is carried outward somewhat beyond the side oli the car to serve as a door arm for cooperation with a door supporting hook 12 which is pivotally carried yupon the end hopper sheet. 'Where the `channel 9 eX- tends over the outstanding door iiange 6 it is formed of reduced depth, the docrcon tacting flange 10 being` offset `trom its normal plane to pass over the flange 6. Thisv provides some excess metalwhich is turned back 'from the upper edge of that portion of the ianged end to provide a wall 13 lying parallel with theweb of the channel 9 but spaced upwardly somewhat therefrom. This wall 13 may be notched out at its outer edge, as at 111, to aecomn'iodate and provide a seat Ifor the ledge 15 oit the hook` A stillening member 7' Il l' 12. The door may be thereby held in partially closed position. ln Figure 2 the hoolr 1.2 is in engagement with this portion of the door arm and the door is shown as being held in partially closed position when the parts are so engaged. It will be ,noted turthermore that when in this position of engagement the approach portion 1G of the hook contacts the upper edge ot the outer flange 17 of the channel1 so that the engagement ot the hook with the wall 13 is limited by the approach portion 1G of the hook strik ing` the upper edge of the ilange 17, which latter thus forms a stop for the hook. By this means a space is provided between the wall 13 and the shanlz portion of the hook for the insertion olf a removable door-prying` .lever 18 which, as shown in Fig'. 2, may be caused to bear against the ledge or' the hook and react against the outer tace of the door to torce the door shut. rlll-1e portion ot the hoot; ledge near the shank ot the hook is, as

. indicated at 19, recessed slightly to provide a` seat Yl'or the lever whereby it is j nfevented 'rom Islipping when so used.

'the turning down ot the end portion of the flange to torni the wall 13 also provides a socket wherein the lever YI8 may be inserted to thereby constitute an extension l'rom the end ot the door spreader for use in n'ianually moving` the door troni one position to another. Vlfhe lever 18 is shown in this latter position in Figures 1, 3 and 4.

in order to pivot the hook 12 to the hopper end sheet 1 a pivot bracket is provided, the same comprisinga base portion 2() adapted to lie directly against the hopper end sheet and an outer or cover plate 21 arranged to overlie the pivot end of the hook. The base portion may be provided with spools 22, one ot which forms a pintle upon which the hook is pivoted. Another of these spools may be employed as a pintle "r'or the hoololocling cam 2l. ll ot these spools torni spacer' for positioning the outer plate 21 with respect lo the base 20. The spools are all pierced and rivets 22% pass. there.n ln'ongh and connect the ouler plate to the base and also connect the entire mechanism to the hopper end sheet 1. rlho spool 22 which serves as a `pivot for the cam 24tis located opposite the stil'tening member 7 and the rivet therefor passes through this stiftening` member. As the spool which constitutes the pivot for the hook is set back somewhat irom the line of the stiftening member v7, it will be seen that the cam is located outwardly ol" the pivot point of the hook and toward the point thereof, the cam thereby stu-ving more eiliectively to hold the hook in engagement with the door. Then the door is completely shut the ledge 15 of the hook seats beneath the outermost flange 17 ofthe door arm and with the cam 24 rotated in the appropriate direction the door will be held lirinly closed and will not become accidentally unlocked because oi the eitlectiveness ot the eccentric cam at the location shown. It will be noted that one of the rivets for alli):- ing the stiilening member 7 to the hopper end sheet 1 is arranged directly behind the hook 12. rlhis rivet is numbered 25 on the drawings and as the hook is preferably formed of section, the resulting cavity in the inner face of the hook forms a pocket for the accommodation of the head of this rivet. By this means a lfull-headed rivet may be employed directly back of the hoolr and the rivet head furthermore constitutes a projection from the car or from the pivot bracket which serves as a limit stop to prevent the hook `from dropping too far down when the door is released. The base 2O and the cover plate 21 are extended somewhat toward the edge of the .hopper in order to form a guide-way for the hook so that it will not shift lengthwise along` the door arm. The hook is thus prevented :lrom creeping oil the end ot the arm by the restraint ot the cover plate 21. At the saine time the hook lies close along the edge of the car and reasonably close to the line oil? the door, where the force is applied to the door arm.

I have thus described a preferred embodiment of my invention. Other embodiments are contemplated within the scope ol. the appended claims without departing from the spirit thereof.
